- Abstract
- In this paper, three derivations of linear frequency concealments were simulated and compared. These three Error Concealment (EC) algorithms use linear frequency re-interpolation. We have implemented and compared different numbers of neighboring blocks involved during the re-interpolation. These three error concealments are Previous Coded Block Linear Error Concealment (PCB-EC), Four Neighbors Linear Error Concealment (4N-EC) and Eight Neighbors Linear Error Concealment (8N-EC). The results show that 4NEC algorithm can achieve the best performance and have PSNR increment by 8.2dB after recovery while other algorithms can only improve 1-2dB after recovery.
